Qiang Tian created HBASE-11146: ---------------------------------- Summary: HMaster instantiates both MasterCoprocessorHost and RegionServerCoprocessorHost Key: HBASE-11146 URL: https://issues.apache.org/jira/browse/HBASE-11146 Project: HBase Issue Type: Bug Components: Coprocessors Affects Versions: 0.99.0 Reporter: Qiang Tian Assignee: Qiang Tian
See HBASE-11096. in 0.99, HRegionServer is the base class of HMaster. master and regionserver share the same run method, the master instantiates both MasterCoprocessorHost and RegionServerCoprocessorHost below is example logs, a coprocessor is start/stop twice--one is for real regionserver, the other is for the RegionServerCoprocessorHost in master. 2014-05-08 00:33:51,632 INFO [M:0;bdvm135:36021] coprocessor.TestCoprocessorStop$FooCoprocessor(66): st art coprocessor on regionserver 2014-05-08 00:33:51,633 INFO [RS:0;bdvm135:47513] coprocessor.TestCoprocessorStop$FooCoprocessor(66): s tart coprocessor on regionserver ... 2014-05-08 00:34:03,166 INFO [main] regionserver.HRegionServer(1624): call stack of stop java.io.IOException at org.apache.hadoop.hbase.regionserver.HRegionServer.stop(HRegionServer.java:1624) at org.apache.hadoop.hbase.master.ServerManager.shutdownCluster(ServerManager.java:975) at org.apache.hadoop.hbase.master.HMaster.shutdown(HMaster.java:1623) at org.apache.hadoop.hbase.util.JVMClusterUtil.shutdown(JVMClusterUtil.java:256) at org.apache.hadoop.hbase.LocalHBaseCluster.shutdown(LocalHBaseCluster.java:437) at org.apache.hadoop.hbase.MiniHBaseCluster.shutdown(MiniHBaseCluster.java:519) at org.apache.hadoop.hbase.coprocessor.TestCoprocessorStop.testStopped(TestCoprocessorStop.java: 114) ... 2014-05-08 00:34:03,215 INFO [main] regionserver.HRegionServer(1629): rsHost code path called 2014-05-08 00:34:03,228 DEBUG [main] coprocessor.CoprocessorHost(258): Stop coprocessor org.apache.hadoo p.hbase.coprocessor.TestCoprocessorStop$FooCoprocessor 2014-05-08 00:34:03,462 INFO [main] coprocessor.TestCoprocessorStop$FooCoprocessor(88): create file hdf s://localhost:8155/user/tianq/test-data/f0c9423c-e505-4feb-907e-c7bd6e16545b/regionserver1399534399680 r eturn rc true ... 2014-05-08 00:34:03,482 INFO [main] regionserver.HRegionServer(1624): call stack of stop java.io.IOException at org.apache.hadoop.hbase.regionserver.HRegionServer.stop(HRegionServer.java:1624) at org.apache.hadoop.hbase.util.JVMClusterUtil.shutdown(JVMClusterUtil.java:264) at org.apache.hadoop.hbase.LocalHBaseCluster.shutdown(LocalHBaseCluster.java:437) at org.apache.hadoop.hbase.MiniHBaseCluster.shutdown(MiniHBaseCluster.java:519) at org.apache.hadoop.hbase.coprocessor.TestCoprocessorStop.testStopped(TestCoprocessorStop.java: 114) 2014-05-08 00:34:03,485 INFO [main] regionserver.HRegionServer(1629): rsHost code path called 2014-05-08 00:34:03,485 DEBUG [main] coprocessor.CoprocessorHost(258): Stop coprocessor org.apache.hadoo p.hbase.coprocessor.TestCoprocessorStop$FooCoprocessor 2014-05-08 00:34:03,493 INFO [main] coprocessor.TestCoprocessorStop$FooCoprocessor(88): create file hdf s://localhost:8155/user/tianq/test-data/f0c9423c-e505-4feb-907e-c7bd6e16545b/regionserver1399534399680 r eturn rc false -- This message was sent by Atlassian JIRA (v6.2#6252)
